The motor used with this pump uses sleeve bearings which require
periodic reoiling. Each motor has two bearings, which should be
lubricated once a year. The bearings are located around the motor
shaft (See Figure 2), at each end of the motor. The oil reservoirs have
plastic plugs covering them. Pull out the plugs and put oil in. Replace
plugs after oiling.
Follow re-oiling instructions on the motor (see nameplate or terminal
box cover). If instructions are not included, re-oil once a year with 30-
35 drops of SAE No. 20 non-detergent or electric motor oil. Do not
over-lubricate.
PUMP
There is no normal pump maintenance. Some work might be required
on the pump when output has been reduced or when seal leaks. This
can be caused by lint build-up around the impeller. Disassemble pump
(See Mechanical Seal Replacement), remove impeller (Ref. No. 5)
and clean out, then re assemble.
MECHANICAL SEAL REPLACEMENT
After pump has been in service for a long period of time, or if pump
has been in severe service, it may be necessary to replace shaft seal
assembly (Ref. No. 3 & 4). Leakage can be detected by a dripping or
flow of liquid from area around motor shaft (Ref. No. 1).
The precision lapped faces on shaft seal assembly are easily damaged.
Handle your replacement seal carefully and read these instructions
before attempting to replace seal.
Refer to Figure 5 for Parts Illustration.
1. Disassemble casing (Ref. No. 8) and casing seal (Ref. No. 7) from
adapter (Ref. No. 2) by removing fasteners (Ref. No. 9).
2. Notice the location of impeller (Ref. No. 5) on shaft. It should be
compressing seal cartridge (Ref. No. 3). Loosen fastener (Ref.
No. 6) and impeller will slide off shaft.
3. Pry seal seat (Ref. No. 4) from impeller recess with a small
screwdriver (see Figure 3).
4. Press old seal cartridge out of adapter by pushing from motor
side.
NOTE:
Use a 11/4” pipe or a socket from a tool set.
5. Clean adapter seal cavity before inserting new seal cartridge.
6. Carefully wipe polished surface of new seal seat with a clean
cloth.
7. Wet the rubber portion of seal seat with a light coating of soapy
water.
8. Press seal seat squarely into cavity in impeller as illustrated. If
seal seat does not press squarely into cavity, it can be adjusted
in place by pushing on it with a piece of pipe. Always use a piece
of cardboard between pipe and seal seat to avoid scratching seal
seat. This is a lapped surface and must be handled very carefully.
9. After seal seat is in place, check that it is clean and has not been
scratched or cracked.
10. Replace seal cartridge. A sealing compound (such as silicon or
Permatex) may be used to insure a water tight fit on outside of
cartridge.
11. Mount adapter on motor mounting face.
12. Replace impeller, tightening it securely with fastener in
approximately same position it had been before disassembly.
(See Step 2).
13. Make sure casing seal is in place on adapter.
14. Replace casing, tightening securely with fasteners.

ROUTINE
Pump should be checked daily, weekly, monthly, etc. for proper
operation. If anything has changed since unit was new, unit should
be removed and repaired or replaced. Only qualified electricians or
service personnel should attempt to repair this unit. Improper repair
and/or assembly can cause an electrical shock hazard.
